Business Review

“Learning about the martial arts has become a wonderful chapter in my life. It has enriched my life, and has given me an opportunity to gain more self-confidence in my abilities to achieve and deal with the daily social challenges that exist today. The various workouts that I attend and techniques shown to me by the instructors at The Self-Defense Institute, whose knowledge demonstrate years of hard work and conditioning, are very valuable to me at this time in my life. Self-confidence has taken on a new meaning that continues to grow within me as I continue to train. Clearly, my choice to train in the style of Kempo Karate, Ju-jitsu, and Kung Fu has been the right choice for me.”
